【Abstract】 The motion of a charged quasiparticle on a linear chain under the action of an electric field with alternating intcrsite interactions is investigated. Exact solutions for the wannier state amplitudes, the propagators and mean -square desplacement are obtained for the case of a uniform electric field. The dynamic localization and the possible confinement are also discussed.更多还原
